Show-cause doesn't mean you can't hire the guy. It means if you hire him, he and the institution must both submit letters to the NCAA stating they both will comply with the restrictions imposed by NCAA. They must report detailed compliance every six months until the penalty expires or employment ends. The risk is if other violations occur, then the school and the coach are both screwed. If you hire the guy and you don't want the imposed penalties, you have to go to the NCAA and "show-cause" as to why the penalties should no longer apply.
In other words hire Pearl now. He just can't recruit until Aug 2014.
